Network Topology

— the physical network

NetInjector routers move notifications along from point to point.

Your NetInjector environment establishes links among routers, and manages these intelligently, so that notifications move efficiently.

The Network Topology interface provides a view of your physical network; you can add routers and servers, as well as establish links among them.

Create a router or server

Your topology begins with the placement of routers and servers. As you develop your network, you can add routers to support new or expanding services.

1. Open the Configuration window.
2. Click in the workspace to create a router or server.
3. At the prompt, create either a standard router, a channel server, or an AIS server.

Note: The default setting for server is channel server. Select only one server to be an AIS.

4. Enter the following information at the prompts

router name: the physical name of the machine

IP address: the machine's static IP address

stage: select stage one for publishing, stage two for subscribing

Modify a router

Your configuration must conform to the physical environment represented by the topological view. If you change the hardware's name or IP address, or entered the information inaccurately, you can modify the node in the topology, or remove it entirely.

1. Left-click a router to access its properties.
2. Click Properties to change the router's name or IP address.
3. To delete a router and its links, click Remove.

Create the network

Once you have defined the routers and servers for your network, you can create links among them. Create your links between stage one and stage two servers.

For example, in the foregoing Network Topology, publisher routers appear on the left; subscriber routers are on the right. The routers are linked such that publishers served by newyork, chicago, and atlanta can publish notifications to subscribers served by dallas, sanfrancisco, and losangeles.

Note: To maximize performance and ensure stability, do not create links between routers serving the same stage.

1. Right-click a router to highlight it.
2. Right-click another router to link to the highlighted one.

Manage the network

You can also use the Network Topology view of your network for fault management.

1. Left-click a router to check router properties and node status.
2. Select Properties from the prompt box to check the name and IP address of a router.
3. Select Node Status from the prompt box to check the availability of the router.

For daily router maintenance, use the Fault Management interface to check router status and to stop processes.
